SWING.

Application filed June 25, 1926. Serial No. 118,557.

My invention relates to improvements in swings. and it consists in the combinations, constructions and arrangements herein described and claimed.

. An object/of the invention is the provision of a swing which is adapted to be actuated by bodily movements of a user or users of the swing and which cannot be overturned accidentally in use and therefore is absolute ly safe for the use of children.

A further object of the invention is the provision of a swing of the character described which can be made almost entirely of lengths of pipe and pipe fittings, and which can be made to accommodate one or more users.

A still further object of the invention is easy to operate. strong and durable. not likely to get out of order easily and thoroughly practical commercially.

Other objects and advantages of the invention will be apparent from the following description, considered in conjunction with the accompanyingdrawings. in which Figure 1 is a perspective view of a swing embodying the invention it appears in a position of rest, 7

Figure 2 is a side elevation of the im proved swing, showing in full. lines the swing in its position of rest. and showing in dotted lines two difierent positions of the swingable frame structure of the device during the operation of the swing, portions of the supporting structure of the device be ing broken away, I I

Figure at is 'a relatively enlarged section substantially along the line 4ll of Figure 3, I

Figure 5 is a relatively enlarged fragmen tary sectional view substantially along the" line 55 ofFigure 2.

The supporting structure of the swing includes a substantially rectangular base frame which comprises a pair of parallel side members 1, which preferably are lengths of pipe, ja pair'of parallel end members 2 which also preferably are lengths of pipe and suitable pipe fittings, such as the street elbows 3 and the -Ts 4: which connect adja cent ends of the side members 1 and the end members'2. The street elbows 8 are attached directly to the end members 2 and the Ts 4 are arranged to connect the street elbows 3 with the side members 1 and are adjusted so that branches 5 of the Ts are turned upward. Standards 6, which also may be lengths of pipe are connected with the upturned branches 5 of the Ts 41. as by means of cooperative internal screw threads on the branches '5 and external screw threads on the lower end portions of the standards 6. whereby the standards 6 will be supported in vertical positions and the standards 6 at. each of the opposite ends of the base frame will be in alignment transversely of the frame. The standards 6 are stayed to the side members 1 of the base frame by brace bars 7 and are stayed to the end members 2 of the base frame by brace bars 8. The base frame may be supported in horizontal position slightly above the earths surface in any suitable manner. as by means of a pair of spaced transverse supporting blocks or ties 9 on which the side members 1- 0f the base frame rests adjacent to opposite ends of the base frame and through which the side members of the base frame may be secured by fastening devices 10. The swingablc structure of the device includes pairs of hanger bars 11 at opposite ends of the sta tionary frame structure,- the respective hanger bars 11 of each pair being connected with each other at their lower ends by a shaft 12 and being supported at their upper ends on the extending adjacent end portions of axially aligned short shafts 13 which are carried by the upper. end portions of the standards 6. at the corresponding end of the stationary frame structure. The short shafts 13 may be rods projected through diametrically opposite openings in the walls of the associated standards 6 as shown to advantage in Figure 5 and retained in place by nuts 14 and washers 15 on the outer end portions of the shafts 13 and fixed collars 16 on the shafts 13 in abutting relation to the inner side portions of the standards 6. The upper end portions of the hanger rods 11 preferably are flattened as indicated at 17 andare provided with transverse openings. as indicated at 18 for the reception of the inner end portions of the shafts 13, the Walls of the openings 18 being formed with counterbores 19 and 20 respectively, the counterbores '19 being adapted to partially receive the fixed collars 16 and the counterbores 20 being adapted to partially receive collars, as at 21, which are in threaded en V cooperativel formed to product race-ways for ball bearings Lock nuts: 23 are in threaded engagement with the extreine inner end portions of the shafts 13 to prevent accidental displacement of the parts which constitute the anti-friction assemblies on the inner end portions of the shafts 13. The lower end portions of the hangers ll also preferably are flattened at 24v and as ij-learly shown in Figure t, are provided with transverse openii'igs 25 adapted to loosely receive the end portions of the shafts 12. The walls of the openings 2d are ei'ilar g'ed at their op I and 27 respectively on the end portions of the shafts l2, the adjacent portions of the walls of the openings 25 and the collars 26 and 27 being' cooperatively formed to provide race ways for ball bearings 28. The collars 26 abut shoulders 29 on the shafts l2 and nuts 30 are screwed onto the end portions of the shafts 12 against the collars 21', thus maintaining the parts of the ball bearing assemblies at the lower ends of the hai 11 in place on the end portions of thesh i is 12. The shoulders 29 may be the end walls of tubular spacer members or distance pieces on the shafts 12 and such spacer members may comprise short lengths of pipe 31 on posite ends to partially receive collarseach shaft 12 and connected at their inner ends by a pipe union or coupling 32, the shoulders 29 then being the opp; ite end walls of the respective lengths of pipe 31, on'each shaft '12..

The swingable structureof the devi it also includes a carrying or riding" frame which comprises a pair of longitudinally extend-- ind ineiinbers 3;; which extend in adjacent parallel. remote with each other for the greater part of their length and have supporting end portions 34 whichare turned downward and slightly toward the ends of the stationary frame structure of the device and are provided at their lower ends with horizontal attaching: lDGllil'iGl'S 35 which are secured on the tubular sections 31 'of the I spaciii'g members on the shafts 12. The sup- 1 porting portions 34: at corresponding ends of the members 33 also diverge slightly from each other toward their lower ends and the members 35 at the lower ends of the memhere 34 at the same end of the ridii'ij'r frame are secured on the respective sections 31 of.

the spacinginember on thecorresponding shaft 12. The members 3 t--33-34 may be lengths of pipeiand the members 35 may be suitable pipe fittings such as Ts, attached to the lower ends of the parts The end portions 34- of each member 33 are stayed to each other by longitudinal connecting bars 36 which may be lei'ifith s of pipe and which in turn are staycrf to each other" interv intermediate their length by a or stay bar 38 which in turn is connected with t e provided on a bicycle One or more of the seats 42 may be provided anda handle bar 4-5 prefcral'ily is p'rm ided for each of he seats 42. Also, a substantially U-shaped stirrup member 416 is provided for use by the user of each of the seats 42,2each stirrup member 46 having a pair of arms 47 pivotally atlacl d at their fpper ends, as 2/ 48 to the inirlbei's 33 and the arms 47 of each of the stirrup members may he stayed to each other by a cross rod 49.

From the foregoing description of the various parts of the dcvice the operation th 'eof may be readily understood. The or users of the device may impart an t oscillatory motion to the riding frame by bodily rockii'ig motion of his body or their bodies and since the hang-er membe s .ljl are supported anti-frictionally at their upper ends, and the riding frame is supported antifrictionally on the hanger members 11, it will be manife t that but slight effort required to effect desirable oscillatory movement of the riding frame. he riding; frame is of less length than the side members 1 of the stationary supporting frame and the hang i: ll at opposite ends of the stationary supporting frame structure there fore will be inclinet downwardly and longitudinally of the device when the riding frame is in a position of rest as shown in Figure 1. and by the full lines in Figure 2. It therefore will beimpossible for the riding frame to be oscillated to an extent sufficient to cause complete revolution of the hang ers about the shafts l3 and moreover the oscillation of the riding frame would be accompanied by an endwise ro'ckin movement of the riding fraine, thus adting to the pleasure of the users of the device. Th e statioiiary supporting frame is of considerably greater len th and -.width than the length and width of the riding frame and therefore the device cannot be overturned in use and the device thus is perfectly safe for use by children As will be understood from the foregoing description from the drawings, the device may be made jp'rincipally of lengths of pipe and pipe fittings.

lot

The length and dimensions of the component parts of the device may be varied according to particular requirements of the service for which a particular embodiment of the invention is intended. For example, the length of the supporting frame and the riding frame of the device will be less when the device is intended for use by only one person than the length of the corresponding parts of a similar device intended for the use of a plurality of persons at the same time.

Obviously, the invention is susceptible of embodiment in forms other than that which is illustrated in the accompanying drawings, and I therefore consider as my own all such modifications and adaptations thereof as fairly fall within the scope of the appended claims.
